Specification forming part of Letters Patent No. 204,100,- dated May A April 30, 1878.

To all whom it may concern:

' Be it known that I, Wo'RrHnveroN SoRAN- TON, of New Haven, in the county 'of New Haven and State of Connecticut, have invented a new Improvement in Machines for Making Paper Felt; and I do hereby declare the following, when taken in connection "with the accompanying. drawings and the letters of reference markedv thereon, to be'a' full, clear, and exact description of the. same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, side view; Fig. 2, plan view Fig. 3, longitudinalsection, Figs. 4 and '5, detached sectional views to illustrate the operation of the machine. v v

This invention relates to an improvement in machinery for making paper felt or'lint, and is an improvement upon the apparatus for which Letters Patent were granted to Joseph Parker and Joseph H. Greenleaf, dated June 19, 1877, assigned to the said Joseph Parker, assignee in this application. In that patent there was a constant feed and several breakers, both rotary and reciprocating, the reciprocating breakers working up and down through the slots; but these breakers do not produce the most satisfactory result, because they fail to rub the surface of the paper upon itself, as by holding the paper in each hand and rubbing the paper between the fingers, which is correctly stated in that specification as the de- The object of this invention is to more perfectly separate the fibers of the paper, that the article produced may be of the softest possible character; and it consists in the construction and combination of mechanism, as hereinafter described, and more particularly recited in the claims.

A is thebed or table, supported on a frame- Work, B, the frame-work'also supporting the operative mechanism. On the bed A, and in guides O, a sliding plate, D, is arranged, to which an intermittent reciprocating movement is imparted bymeans of a grooved cam, D on the driving-shaft D through a lever, D, in connection with said slide, the groove in the cam being such that it will hold the slide forward, as in Fig. 3,

A bove this slide D is a .bar, E, arranged so; that its forward edge comes in line with the edge'of the slide, and, asseen in Fig.3, forming one jaw, while the slide D forms a secondjjaw, between which the paper to be operated uponpasses. On the driving shaft there is a cam arranged, (indicatedinf broken lines,) which oper: ates upon the jaw E throughlevers E} E to raise and lower the. jaw E, and relatively to the cam D, so that the jaw rises. just before. the slideD retreats anddrops just beforethe slide D advances. This jaw Ev moves with the slide D, being. held there by guides E9,

which govern the vertical movement of the jaw E and connect it to the slide D.

Immediately forward of the edge of the jaws E and D there is a pair of jaws, F G. These jawsare arranged in a vertical carriage, F, working up and down in guides F and caused to so work or reciprocate by means of an eccentric or crank, F connected to the carriage by a pitman, F. This reciprocation is rapid, and the driving-shaft D and the crank-shaft F are connected together by intermediate gears, so that power applied to one shaft-say the crank-shaft F will communicate power to the other shaft, D the relative velocity of the two, in consequence of such gearing, being so that the jaws F G will reciprocate several times, while the jaws D E are stationary. These jaws F Gr have also an opening movement, which is produced by means of a horizontal slide, H. (Seen in Fig. 4.) This slide has two inclined grooves, 01, 11, each connected to one of the jaws F G, and so that when the slide H is drawn outward the incline will cause the jaws to open, as seen in Fig.4, and, forced in the opposite direction, will cause the jaws to close, as seen in Fig. 3. The slide H is moved by means of a cam (not shown in Fig. 3) acting upon a stud, cl, on a rod, L, which is connected to a, slide, L',,in the frame. From this slide a lever, L ,'is connected to the slide H, and hung upon a pivot, 6, between.

As the slide H is arranged in the vertical ver L? is therefore connected to that carriage and moved up and down with it; hence the use of the intermediate slide L to connect the lever L with the rod L.

On the rear of the machine is a shaft, N, on which the paper to be operated upon is wound. On the forward end. there isa similar shaft, which takes up the paper after it has been operated upon. This completes the construction of the machine.

Its operation is as follows: The paper is introduced between the jaws E D when in their open and rear position, as seen in Fig. i

'1 The combination of the intermittent horizontally-moving jaws E D, combined with the 4, and also between the jaws F G when in their open position. The two pairs of jaws then close upon the paper, the jaws F D advancing toward the jaws F G, and the jaws F G, reciprocating rapidly, double or fold the paper between the two pairsof jaws,

as indicated by the solid black line f in Fig. 5, and the paper is rubbed uponitself and between the two pairs of jaws, and until the fibers are so completely separated as to make the disintegration complete. In that condition the paper presents the appearance of a light mat of lint. This operation performed on a small portionof paper, the jaws open, as in Fig. 4.; that part already operated upon is drawn forward; the jawsE D and F G, taking each-pair in a new place, presentthe next adjacent surface for a like operation, and so on, working the paper, section after section, until the whole is reduced to the required state.

To draw the paper forward so soon as the jaws open, a. ratchet, P, is arrapgedion the be turned to draw the paper forward intermittently, but as fast as worked upon.

This machinediffers from the Parker and Greenleaf machine referred to, in that thefeed is intermittent, enabling the requisite rubbing of the paper upon itself, asdescribed.

The roll M is not essential, as the paper may be introduced in the form of sheets.

I claim' reciprocating jaws F G, the said two pairs of jaws workin g together to bring. the paper between the said two pairs of jaws, and-operatingupon it in that condition, substantially as described.
